Hello ezideas - First I suggest verifying that there is enough water pressure coming into the unit and that it is at least 120F. Do you noticed if the spray arm will rotate freely or if it is damaged? If so, the spray arm assembly may need to be replaced. Connect with a professional to accurately pinpoint any potentially more serious issue.
Hi, i had this sand residue just on the top shelf and found that the upper spray arm was not rotating around. (I opened the door a few times when it was washing to find the spray arm in exactly the same position). I had a quick look at the spray arm holes but did not notice any obstructions... However on closer inspection, I discovered a small hole pointing sideways at each end of the spray arm. The spray from these holes propel the spray arm to rotate. Both were blocked by a small ball of hair like substance. I had to use a needle to remove this and this solved my problem.
Position the spray arms in a certain position. Activate the dishwasher for a few seconds and then examine the position of the spray arms. If the upper spray arm has not moved, then either there is no water coming to the spray arm or the spray arm is clogged.
Possible causes of spray arm inefficiency: Loading large or tall items in the lower basket which stops the arm revolving. Upper spray arm split along seam. Upper spray arm blocked. Under dosing of powder causing foam and reducing upper spray arm water pressure. Blocked strainers reducing water to circulating pump, therefore reducing upper spray arm water pressure. inefficient wash motor impellor (faulty)
In my experience, you probably have a clog in the spray arm/arms for the top rack. Take the arm(s) out and see if the holes in them are clogged. Rice, plastic wrappers, and glass from dishes that broke in there are the most common culprits I've seen.
maybe not... if unit is incorporating more than one spray arm,chances are the upper spray arm is not getting water.pull top rack forward,gaze under top rack near rear manifold.slowly push rack back in.notice if manifold inserts into upper wash feed.if so,possible motor issue. if not,bingo was his name-o!
The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm. Assuming
the top spray arms are clear of debris, remove the lower spray arm to
access the wash motor. Remove the 4 torx screws and the filter
(accumulator assembly). Remove the torx screw and the inlet protector
that covers the chopper assembly. Make sure the chopper is not broken
(broken chopper will fill with debris and block water flow). While
holding the chopper blade, reach inside the "D" shaped opening on top
of the motor and spin the wheel/motor by hand in each direction to make
sure either the chopper gear or the motor gear that drives the chopper
is not broken. Replace the chopper if necessary (part # 8268383). If
the motor gear is broken, replace the sump and motor assembly (part #
8535150). Remove any debris from the sump area in the process. You
don't have to because the door will be open, but if you feel more
comfortable shutting off the power to the dishwasher, do so. Good luck!
only the top rack isnt getting clean? there is a little plastic
circle in the middle of the bottom of the upper spray arm. turn it
counter clock wise to pull the upper spray arm from the upper rack.
make sure that isnt clogged and the spray holes are not clogged.
the piece that the bottem spray arm plugs into and
runs along the back wall of the tank to the top is called a feed tube.
pull the bottom spray arm out. now you can see the part of the feed
tube that feeds the upper spray arm water. does it pop out freely and
easily? if so then you need a new feed tube, if not then its most
likely your not achieving the right water level or your impeller
connected to your circulation pump(motor) is clogged not supplying
enough water pressure to travel up the feed tube to spin the upper
The spray arm is controlled by the force of the water. There is no motor running the spray arm. If water is not getting to the spray arm, then it won't spin. It may be plugged with detergent etc. Just a note re. detergent. You shouldn't use hard or caked detergents.
